Ok... Here goes nothing..

The 360 has the worst Directional pad I've ever used.

The PSP has the worst analog stick(or should I call it stub) I've ever used.

The DS's L and R buttons jam from dust collect too much for their own good. (DSLite at least)

The PS3's Analog layout  and mushroom-shaped analog sticks hurts my thumbs.

The fact that I have to be 6 feet away from my Wii for it to register any of my gesture-based actions is awful.

Thank you.

And then?

I can't refute this as I have not used it, but X-boxs is awful I know

Not used it extensively but it looks awkward

The DS's L and R buttons jam from collection dust too often then they should. (DSLite at least)
Again, not used it much

The PS3's Analog layout  and mushroom-shaped analog sticks hurts my thumbs.
By analogue layout I assume you mean the two control sticks.... and I agree on that part... I don't see how convex sticks hurts your thumbs though

The fact that I have to be 6 feet away from my Wii for it to register any of my gesture-based actions is awful.
Bollocks... you don't know how the Wii works then.... gesture based motion controls will register from anywhere within range (0 feet up to at least 30 feet if not more, although it can depend on the environment)... Hell I can set up Wii Sports downstairs and play bowling with a Wii remote upstairs in the opposite corner of our house.(although I obviously can't see what's going on)

Perhaps you are thinking of the Infra Red controls? In which case they should work as close as 1 metre if you set the sensitivity correctly (that's 3 feet btw) mine works perfectly from about 4-5 feet away.... and I play games in a box room... If you are needing to be nearer to the TV than I am in my room then I feel sorry for you and the cupboard you live in.

Thank you.
